If I pin and weld this muzzle brake on a 13.9 barrel will it end up being over 16”? Expert Answer

The manufacturer does not state the length of the Yankee Hill Machine .30 CAL Q.D. Muzzle Brakes. I recommend contacting YHM to confirm the length of the Yankee Hill Machine .30 CAL Q.D. Muzzle Brakes.
